TO lALL WHOM IT MAY CONCERN I Be it known that I, J. J. E. LENnin,.of Paris, France, haveeinvonted au Improved lelegraphing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of tbe same, reference being had to the accompanying drawing and to the letters of reference marked thereon. l My invention consists of certain devices, constructed and operating as fully described hereafter, whereby facsimile copies of written or printed messages or diagrams may be transmitted from one extremity' of a tele; graph line to the other. V

'In order' to enable others skilled in the art to makeand use my invention, Iwill now proceed to describe its construction. and operation,.reference-being hadrto the accompanying drawing, which forms a part of -this speci- Hcation, and in which? "Figur'l is a side elevation-fof one of theinstruments used in my improved tclegraphing apparatus.

Figure 2, an end elevation, looking in the direction of the arrow 1, lig. 1. l `Figure 3, a plan view. Figure 4, a sectional elevation on the line 1-2, iig.' 1, looking in the direction of the arrow. Figure 5, a plan view of another instrument used in the apparatus; and `Figui-'esti and 7, detached views of parts of the apparatus. Similar letters refer to similar partsrtiiroughout the several views. i The apparatus consists Vof a dispatehinginstrument, A, and a receiver," B, (figs. 1, 3, and 5,) each instru? ment being situated at onetf'the extrcmi'r/ier'of the line or wire through whiclimesseges are to he sent. `andV being connected with ,the usual galvan'ic batteries by suitable wires.V To the base-plate, C, of the dispatcher, A, are secured a framework, D, and alframe, D', the lformer containing a train of wheels, E, to which motion is imparted by a spring -or weight, and on thc `projecting-end of one ofthe shafts .of this `train-is a cog-Wheel, t, the-teeth of whichl are adapted to those of a similar wheel, t', on a screw spindle, F, the journals of the latter turning in the framesD and D; In the frame D turns one end of .a shaft, G, the opposite end ofwhich is so connected to the end of one of the shafts, u, of the train E that it may be readily detached from or (after a slight lateral adjustment) may be 'turned independently of the said shaft, u. To the shaft G is secured a roller, H, within a recess, 11:, in which ts a bar, a, the latter being `secured in its place by spring! catches b b, fig. 2, which a-re hung to the ends of the roller and extend over the projecting `ends of the bar. 0n the screw F travels a nut, c, which is attached to or forms a part of a frame, I, a roller, d, at theunder side of the latter resting -on a plate, d', secured to the edge of the base-plate C. To the nut c, or to the frameLis hung a lever,`J, the forward pointed end of which projects overthe roller H; and to the rear-end of the lever is secured an armature, e, which is directly above the ends of an electro-magnet, K, secured to the frame I. In

p suitable bearings, at theside of the frame D, turns a vertical shaft, Ina bevel pinion on which 'gears with a bevel-wheel on the projecting end of one of thc shafts f of the train E, and to the upper end of the shaft L are hung two double Yanes or wings M M., each of which is weighted at its lowerend. To thevane M is secured a spiral spring, lr/,and the opposite end of the latter is connected to a pin, which is 'adjustable in a slot, y', i

in the vane M. To the. shaft L i`s secured a metal disk, N, in the edge of which, at equal distances from each other, are ten blocks z' z' of /i'vory or other insulating material; and against the edge of this disk bears a wire' or'spring, j. To a shaft,-7:, turning in hearings im the frame D, is secured an arm, l, an armature at'oue end of which is directly abovethe ends of an electrosm'agnet, O, the opposite end of the arm l(wh`en in the position shown in iig. 4) being in contact with a pin, m, on a disk, n, seouredto the'shaftlk, thereby preventingthe revolution ofthe shaft and the movement of the train. The receiving vinstrument B is precisely like the `dspatcher.A', excepting that the vertical shaft L', insteadV of having a disk N, is provided with a hub of soft iron, from which project ten radial armsor spokes, q q. To brackets secured to the frame Dis attached an electro-magnet, P, the ends of which are almost within range of the ends of the `arms gay, the wire which surrounds the magnet P being connected with the arm j, which bears against the disk N of the dispatcher. Amessage is written with a non-conducting ink upon a sheet of foil, or paperV having a metallic or conducting surface; this sheet is then lapped round the roller of the dispatcher, its ends being securedin the` recess :c by the bar a. -A sheet of .white paper is wrapped round the rollerV H cf l the receiver, and onthis `sheet is placed a sheet of transfer paper, the ends oflboth sheets being secured in the recess z by the bar a'. The frame I in each instrument is brought close'to the frame D', and the operator starts both machines simultaneously by establishing a circuit, which magnetizes the electro-magnet O, draws down its armature `and thus removes each arm Z frcm contact with the pin m on -the-adjacent shaft f.- As the screws F F' and the shafts G G' and L L' revolve in the'direction of their arrows, the rollers H H will revolve quickly, and the frames II' and their levers J J' will be carried slowly towardstheframes D. So long as the point of the lever of the dispatcher is in contact with the metallic surface of the paper onthe roller H an electric current is i communicated to theelectro-magnet K' of the receiver', the armature e' is heldv in contact with the magnet, and the point of the lever J' is free from contact-:with the surface of the paper `on the lroller H'. As soon, Vhowever,as the point of thelever J passes from contact with the Ametallic surface on to an ink mark, the electric current isbroken, the magnet' K' no' longer attracts the armature e', and the point of the lever J is brought -against the transfer paper, from which almark' is thustransferred to the plain paper beneath, this mark being equal in length to the extent of th rotation of the cylinder while the lever is in Acontact with the latter. As soon as the ink'mark is removed from contact with the lever J and the point of the latter is again brought against the metallic surface, the electric current will b e again 'established audthey lever J will be raised'v from contact with the roller H'. As the roller H continues its revolution, and as the frame I travels .slowlytowards the frame D, nearly every portion of the surface of the roller H will be brought in contact with the point of the lever J, and currents will bealternatcly established and interrupted, as before described, the lever J' rising and falling as the lever J passes from or into contact with the inl: marks on the roller H, and producing lines or dots on the paper wrapped on the roller. H', corresponding in length, form, and position to thoseon the roller H; a fac simile copy of the dispatch on the latter roller being thus obtained.

As it is of the utmost importance that the rollers H H' and the frames I I' of thetwo instruments shall move at preciselythe same speed, the speed of the operating mechanism in both instruments is regulated by the devices connected to the shaftsAL L' in the following manner: So long' as the arm is in contact withthe metallic portion ,of thc dish N, a'n electric current will be established between thcarm j and the electro-magnet P, this current being interrupted and thc magnet becoming passivewhen the arm j is in 4contact with one of the insulated blocks z of the disk. The regulator of. the receiver B is so adjusted that two of the arms g q (when both machines move at the same speed) will be exactly opposite the ends of the magnet P when a metallic portion ofthe disk N isin cony -i tact with the armj, that is, when the magnet I is active. Should the shaft L acquire a greater speed than the i shaft L', a metallic portion of thedisk N will be brought against the arm j before any of the arms q are oppoi site the ends of the magnet P; the latter, therefore, being magnetized, (before the -arms are in their positions i will attract the arms approaching it, and thus accelerate the motion of the shaftL'. In like manner, should the shaft L revolve at a less speed than the shaft L the arms q q'of the latter 'will arrive opposite to and will pass or aimost pass the ends of the magnet P before the latter becomes magnetized. When this change is effected, however, the arms nearest to, but passing from', the ends of the magnet will be attracted, and their motion from the magnet,'and consequently the revolution of the shaft, will be retarded. y

The transfer paper used in this apparatus may be covered with amixture of any suitable coloring material and glyccrine, the latter preserving the color moist so that it may be easily transferred from one paper to the other. A copyof thedispatch may also be transferred to another sheet of paperby placing the two sheets in vcontact and subjecting 4them to the action of a press.

- `A secret message may be forwarded by writing the message with a non-conducting ink' corresponding in. color withthe paper it is written upon. A dispatch also may be preserved from the knowledge ofthe operator who receivesit by securing together the edges of the transfer and receiving sheets before they are placed on the roller H'. Instead of using transfer paper, the surface of the roller H' may be inked', and a transparent paper may be used, on to the inner side of which the'ink from the roller is transferred by thepressure of the lever J', thedispatch being read through the paper. 'lo give additional security to the dispatch,stamps containing private seals or signs, printed on metallic surfaces with non-conducting ink, may be secured to the paper containing the message to be forwarded.

Magnetized steel may be substituted for soft iron in' the construction of the electric gearing and for the electro-mag`net of the receiver, this substitution obviating the necessity of employing two wires.

Flat or curved vibrating plates may belsubstituted for the revolving rollers H H' for holding the sheets on which the messages are written or to which they are transferred; or a suitable lever or pencil may becaused to traverse rapidly from one end of the holder to the other, the holder being turned or adjusted to aslght extent after the passage of the pencil or lever in either direction, so that the 'points of the lever may be brought into fa contact with every portion of the surface of the-paper-beneath it." I
